In a few weeks, the Houston Press will publish a Texas road trip guide that will challenge readers to ride from the known to the unknown. The Lone Star State is 268,820 square miles — almost twice the size of the entire country of Germany — and when exploring such a vast place, people need to eat. For the most memorable trip, skip the ubiquitous chain restaurants that line the highways and choose some of the best and most historic restaurants in Texas.

Here are ten restaurants picked from all across Texas that are essential to the journey. Look for more in our forthcoming Big Tex Road Trip guide, and leave your own suggestions in the comments below!

Hugo's, 1600 Westheimer

If a chef has been a James Beard finalist five times, that means there’s probably good reason for it. In Hugo Ortega’s case, there are several and one of those reasons is his eponymous restaurant, Hugo’s. It first opened in 2002 and originally was created to showcase interior Mexican cuisine. At the time, Houston had plenty of Tex-Mex options, but Ortega didn’t see examples of the food he had grown up with, so he and wife and notable restaurateur Tracy Vaught changed that.

The sumptuous Sunday brunch is always packed with Houstonians helping themselves to all-you-can-eat ceviche, roasted fish and moles. All of that is available through the rest of the week, as well as appetizers and entrées, but that’s just a small portion of the extensive menu. There are hearty dishes, like cabrito or tender roasted goat, and one of the most interesting and flavorful vegetarian platters found anywhere.

Ortega’s brother Ruben leads the pastry program, and the restaurant even makes its own chocolate from roasted cacao beans, so splurges like the cinnamon-laced hot chocolate and pyramid cake are absolute musts.

After 104 years, Gaido's has still got it. This luscious crab cake with beurre blanc was wonderfully balanced between lump crabmeat and panko.

It’s almost impossible to think of Galveston dining and not think of Gaido's. It was founded in 1911 by San Giacinto Gaido and is still family-owned to this day. It has not only long been a bastion of Gulf seafood, but also helped define the marriage of coastal cuisine and white-tablecloth dining.

Don’t-miss dishes include the trio of soups — gumbo, bisque and the soup of the day — fresh Gulf oysters and the famous fried platter of Gulf shrimp, seasonal seafood, tenderloin of Texas catfish and “stuffing balls,” close kin to hush puppies.

Fearing's, 2121 McKinney, Dallas

Dean Fearing is one of the fathers of Southwest cuisine, along with chef Robert Del Grande of the newly rechristened Cafe Annie in Houston. (Fun fact: The two chefs are both James Beard Best Chef Southwest winners, fast friends and musicians who not only have played for events but actually cut an album together called Bliss & Blisters.) After spending 20 years as the executive chef of the prestigious Mansion On Turtle Creek, Fearing established his namesake restaurant in the Ritz-Carlton in Dallas.

There, diners can experience the Southwestern cuisine that made Fearing famous, including Dean’s tortilla soup and Dr Pepper-braised rosewood ranch short ribs with "loaded" whipped potatoes and crispy tobacco onions. The chef, though, has never stopped experimenting with other cuisines, so don’t be entirely surprised to see unusual, sophisticated dishes like Tsukiji Market hamachi crudo with hami melon, candied prosciutto, marcona almonds and ponzu pearls on the menu.

Check out the video that features Fearing's chef de cuisine, Eric Dreyer, and pastry chef, Jill Bates, making some of the restaurant's notable dishes.

Joe T. Garcia's, 2201 North Commerce, Fort Worth

Joe and Jesusa (“Jessie”) Garcia (who became known as “Mamasuez”) started a little 16-seat Mexican restaurant known as “Joe’s Place” in 1935.

Joe died too soon, and Mamasuez and youngest daughter Esperanza “Hope” Lancarte were the ones who kept the business going. To this day, the restaurant is still family-owned and -operated. Hope became the next grande dame of the business until her death in 2014, and the kids of the family have all grown up in the business.

The restaurant grew up, too, and these days, Joe T. Garcia’s takes up an entire city block and can seat 1,200 people. It was named one of “America’s Classics” by the James Beard Foundation in 1998.

Among the features are big, gorgeous patios with gurgling fountains, where diners enjoy classic Tex-Mex dishes like fajitas, tamales and flautas with, of course, a margarita on the side.

Jucy's grinds its own beef and makes some of the best burgers in Texas.

Jucy's Hamburgers, Longview

Jucy’s Hamburgers was established in 1980 and has been repeatedly cited as having some of the best burgers in Texas, including by Texas Highways Magazine in November 2015. The secret to this place's burgers and fries is a lot of hard work. Jucy's grinds its own beef and cuts the potatoes for the fries fresh every morning. There are, of course, classic hamburgers and cheeseburgers, but other options include toppings like blue cheese and grilled onions.

The menu is charming, and while the burgers are the big draw, old-school lunch items like Frito salad and the hamburger steak plate with grilled onion are tempting, comforting options.

Jucy’s has now grown to five locations and even serves classic breakfast fare like omelettes, pancakes and taquitos.
